Description
Summary:High resolution image combination and processing plays an important role in today's satellites' remote sensing applications. This paper presents an image recombination and processing system for one-dimensional multi-strip CMOS image sensors (CISs.) The proposed system takes advantage of the satellites' linear moving property to control the exposure time of CIS and provides the real-time ability to generate 11,200 × N high- resolution image for satellites' remote sensing applications. The details of hardware design to meet real-time requirement are given out. The prototype, which contains four strip CISs, is implemented to verify functionality and capability of real-time image acquisition and combination. The implementation results show the proposed system, which demands four times larger throughput than the prototype, is feasible in a chip.
